I just calculated 25% of the chord and came up with 3.6 inches from the leading edge, but If anyone out there has one set up they could measure it because it was proven in there flight so maybe I can get a more percise measurement. thanks again. from the leading edge of the wing.Im looking for just stable flight first time, the manuals dont help much ,Thanks email me ASAP

I don't know, the instructions in the manual seem pretty clear to me. Section 25 on Pg 37 says 1/8 inch behind main spar which is under the back edge of the wing sheeting. IAW the CG is 1/8 behind the sheeting rear edge.

Is this enough?

THANKS BRUCE Ill find that spar

All you really need to find is the back edge of the sheeting.
